Resumo(s)
The KPB crisis is one of the major biological crises that affected the Earth at Phanerozoic times. There is still an acrimonious debate
on the nature and origin of this mass extinction: proponents of the idea that
large bolide impacts caused most of the Phanerozoic mass extinctions are
opposed to those who favoured a terrestrial origin linked to continental flood
basalt eruptions of the Deccan Traps. The major limitations reside in the
difficulty to date with precision the stratigraphic position of Deccan traps
pulses since direct markers are still missing.
